Reclassified Grid | Grid (output) | RESULT | Reclassifed grid. | |
Options | ||||
Method | Choice | METHOD | Select the desired method: 1. a single value or a range defined by a single value is reclassified, 2. a range of values is reclassified, 3. the lookup table is used to reclassify the grid. | Available Choices: [0] single [1] range [2] simple table [3] user supplied table |
old value | Floating point | OLD | Value to reclassify. | |
new value | Floating point | NEW | New value. | |
operator | Choice | SOPERATOR | Select the desired operator (<;.;=; >;.); it is possible to define a range above or below the old value. | Available Choices: [0] = [1] < [2] <= [3] >= [4] > |
minimum value | Floating point | MIN | Minimum value of the range to be reclassified. | |
maximum value | Floating point | MAX | Maximum value of the range to be reclassified. | |
new value | Floating point | RNEW | new value | |
operator | Choice | ROPERATOR | Select operator: eg. min < value < max. | Available Choices: [0] <= [1] < |
Lookup Table | Static table | RETAB | Lookup table used in method "table" | 3 Fields: - 1. [DOUBLE] minimum - 2. [DOUBLE] maximum - 3. [DOUBLE] new |
operator | Choice | TOPERATOR | Select the desired operator (min < value < max; min . value < max; min .value . max; min < value . max). | Available Choices: [0] min <= value < max [1] min <= value <= max [2] min < value <= max [3] min < value < max |
minimum value | Table field | F_MIN | ||
maximum value | Table field | F_MAX | ||
new value | Table field | F_CODE | ||
no data values | Boolean | NODATAOPT | Use this option to reclassify No-Data values independently of the method settings. | |
no data values >> value | Floating point | NODATA | new value | |
other values | Boolean | OTHEROPT | Use this option to reclassify all other values that are not specified in the options above. | |
other values >> value | Floating point | OTHERS | new value |
